CVE-2026-25765

Estado: AnalizadaMedia (5.8)—

Faraday is an HTTP client library abstraction layer that provides a common interface over many adapters. Prior to 2.14.1, Faraday's build_exclusive_url method (in lib/faraday/connection.rb) uses Ruby's URI#merge to combine the connection's base URL with a user-supplied path. Per RFC 3986, protocol-relative URLs (e.g. //evil.com/path) are treated as network-path references that override the base URL's host/authority component. This means that if any application passes user-controlled input to Faraday's get(), post(), build_url(), or other request methods, an attacker can supply a protocol-relative URL like //attacker.com/endpoint to redirect the request to an arbitrary host, enabling Server-Side Request Forgery (SSRF). This vulnerability is fixed in 2.14.1.

Antes de la versión 2.14.1, el método build_exclusive_url de Faraday (en lib/faraday/connection.rb) utiliza URI#merge de Ruby para combinar la URL base de la conexión con una ruta proporcionada por el usuario. Según la RFC 3986, las URL relativas al protocolo (por ejemplo, //evil.com/path) se tratan como referencias de ruta de red que anulan el componente de host/autoridad de la URL base. Esto significa que si alguna aplicación pasa entrada controlada por el usuario a los métodos get(), post(), build_url() u otros métodos de petición de Faraday, un atacante puede proporcionar una URL relativa al protocolo como //attacker.com/endpoint para redirigir la petición a un host arbitrario, lo que permite la falsificación de petición del lado del servidor (SSRF). Esta vulnerabilidad se corrige en la versión 2.14.1."
